IMPROVEMENT IN ROAD-SCRAPERS.

Specification forming part of Letters Patent No. 171,433, dated December21, 1875; application filed' November 18, 1875.

To all whom it may concern Be it known that I, FRIEDRICH W. sorrow, ofMount Pleasant, in the county of Henry and in theState of Iowa, haveinvented oer tain new and useful Improvements in Road- Scrapers and dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawingsand to the letters of reference marked thereon, making apart of thisspeci fication.

The nature of my invention consists in the construction and arrangementof a road-scraper, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in which-Figure 1 is a side elevation of my roadscraper, showing the same turnedover for moving from place to place. Fig. 2 is a longitudinal section ofthe same in position for use.- Fig. 3 is a front View of theroad-scraper with d, having a wheel, G, upon each end, thus supportingthe road-scraper on said Wheels. On the bottom of the scraper-box A, atthe rear end, are formed or attached shoes 0 e, as shown, to preventwear of the box when in use. On the rear of the scraper is aspring-hook, H, to catch on the cross-bar or bail E of the handles, forholding it when the scraper is loaded. I is thetongue, havingacross-bar, J, atits rear end, and metal straps L L extending from thetongue under and in rear of the ends of said crossbar, and the extremeends of said straps are placed upon the pivot-bolts a a. Near one end ofthe cross-barJ is pivoted a spring-hook, 1?, which is to catch on a pin,2', projecting from the side of the handle D, to hold the scraper whenemptied. In operation it will be seen the scraper is raised and loweredat will by means of the handles D D, as the scraper is hung on a lineaway from the axle.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The spring-hook P, attached to the tonguecross-bar J, in combinationwith the handles D,-pin z, scraper A, and hook H, substantially as andfor the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this18th day of October, 1875.
